It has always surprised me how low the number of interior design teams using Revit has been – often even not used by interiors teams in large firms where the majority of the architecture projects are being delivered using Revit. For me, Revit has always offered significant benefits to my projects, ever since I made the decision my team would move away from 2D CAD packages and into Revit for all projects back in 2007. That’s right -all projects. I doesn’t matter how big or how small a project, or if there are existing drawings in a 2D CAD format, or even if my new design team doesn’t yet know Revit – all the projects I have lead and worked on for the last 7 years have been primarily designed and documented in Revit. Recently, I’ve been pleased to find more interest in using Revit for interior design with a number of people mentioning to me both in person and on twitter that they want to know more about the benefits of Revit for interiors. So I thought it might be time to write a blog post (which has turned into 2 parts) on the main benefits of using Revit, as well as tips for optimising Revit for interior design teams. Today’s post is focussed more on the information benefits and setup of Revit whilst the next part will discuss Revit as a design and visulisation tool.

The Power of Scheduling
When asked recently on twitter for my number one tip for using Revit for interiors, it was to make use of scheduling. From the very beginning of using Revit it was the scheduling and tagging abilities of Revit that have paid off for my projects. At its most basic, the use of schedules for room areas or workstation numbers saves time every time. Scheduling furniture, fixtures and signage is also a breeze – and even better visually now that Revit 2015 allows us to incorporate images – finally! I am sure this change will play a big part in convincing interior designers to use Revit. Door schedules are great too – although come with their own challenges, as do finishes schedules (material take off in Revit terminology).

Anything you used to schedule in word or excel, you can schedule in Revit, so why type everything twice and risk making mistakes? There are a couple of key issues to be aware of when using Revit for schedules. Firstly you have to remember that your schedule is based on your model – if there is garbage in your model (eg two chairs on top of one another, or chairs off in space), there will be garbage in your schedule. The other is the visibility filters set in the schedule, what is not visible is not counted. If the schedule name is Level 23 Workstation Schedule, but the schedule filter is set to Level 22 then its not of much use (just as if someone accidentally counted off the wrong plan!). Schedules always need to be manually checked when first set up, and then some ongoing common sense checking as the project progresses.

Schedules themselves are also great to help you with checking. I use various kinds of schedules for BCA and GreenStar calculations and checking and even expanded schedules to check filtered or totaled schedules. Taken further schedules can become the basis for Room Data sheets created in excel, word (or other 3d party softwares). For an example using excel you can see my previous post What’s in a Room?

If you are interested in more on Revit Scheduling I have presentation on slide share called Informedesign which is primarily about using Revit and its information (often conveyed via schedules) to support your design process.

At the end of the day, the value of scheduling lies in its ability to free up time to spend more time doing what we love – designing. But before we get to the benefits of Revit in the design process, I will touch on the other key aspect of freeing up your time in Revit – leveraging repaatative content.

Revit loves repetition
Its true, Revit loves repetition. Many people believe that means its not valuable for the one off – but it is and I am going to talk more about that next post. However, as with scheduling you use Revit’s power of repetition to free up your time to focus on the one off items and area, because that is where we should focus our efforts as designers.

Two areas of Revit are key for repetition, families and groups. Families are discussed further below as part of your libraries but groups should also form part of your strategy for repetition. I’ve written extensively before about groups – so once you have got the basics of this post, you can go read more about groups here.

Building your generic library
Interior designers and BIM managers alike are often dismayed by the thought of modeling everything in an interior design project (or even worse – by starting to think about what could go into a every project), every piece of furniture and every material known to man. The answer to this dilemma – is that you don’t necessarily have to. If its your first Revit project and your aim isn’t to deliver a full BIM project then don’t try to – you will overwhelm yourself and struggle to deliver. Start off with a little and build up over time. Focus initially on two areas, one is the more generic content and the other is the areas where Revit assists your design thinking.

By generic content, I mean the components you use most frequently in projects. This will differ depending upon your firm, the types of projects you do and the types of 3d imagery you need to output. For me, primarily I am designing workplace and educational projects. My basic set of generic content therefore includes task seating, a few different lounge, meeting and cafe seating styles and a couple of shapes and styles of tables with easy to modify sizes and bases. At its most basic joinery and equipment may start out as a family that just contains a box.

Focus on your outputs. If all you are producing is 1:100 test fit planning – you are wasting time modeling every cupboard and agonising over what each chair looks like. As long as you have your plan objects looking right, you can produce your deliverables (and schedule too). Over time you can start to develop your 3D detail or information for different areas over time depending upon your design stages and outputs. For example, while we will end up modeling the casework in a store room eventually (in order to document it), we probably won’t look at it in anything other than plan until quite late in the project (or you might never even need to). By contrast, the 3D development of key spaces such as reception will begin much earlier and may include more specific furniture, joinery and finishes even from the very first presentations. Workstation areas would be likely to be in between. We model almost everything in 3D, so we can create massing type images and flythroughs, it is then the level of detail that differs across the objects in different areas. This also helps to contribute to a more sketchy feel earlier in the design process (as do the new 2015 sketchy lines).

I would also say, don’t rule out using supplier content but don’t rely on it exclusively. For anything you are going to use over and over again, you can start from a supplier family but make sure you do some sort of QA to determine if its suitable for your ways of using it – for me key things are that it is the right way around (all Hermans Millers chairs are backwards) and that is has a 3d plan component to it so it will represent as white in views with colour schedules applied. Beyond that I may also go further with replacing parameters and materials if my uses for it require this. (eg for scheduling) Its great to see the range of furniture and fixtures available as Revit families are growing – examples currently available include Haworth, Steelcase, Caroma and Britex (you can find a good starting list here at IGS website).

The other key part of your generic content is materials. It much more efficient to have a library and templates that already contain basic finishes such as white powedercoat, black laminate or stainless steel complete with information and keynotes that then doesn’t need to be recreated in every project. Again supplier sources such as Dulux free Colour Atlas for Revit app or RTV’s Revit Paint (which includes Dulux, Resene and more) can also help build up your material options quickly.

Next post I will talk more about Revit materials and finishes as well as how to use Revit to power your interior design process, but also about some of the limitations of Revit for interiors (Autodesk hope you will be reading!). In the meantime, are you using Revit for interior design? What are your tips? Or is your firm starting to think about it? What makes you hesitate? Are you just starting out with Revit for interiors? What’s driving you batty? (because Revit does do that too, even to me some days!)

In fact the term “simulation” is here applied to what we in architecture, interior design or engineering would use the term, models – specifically computer models. Part way through the book, our use of this term in architecture is actually discussed – that we use this term in resisting change, feeling a need to define the computer outputs in a language with which we are familiar.

It was interesting to see the understanding and language of computer simulations discussed across a variety of fields including architecture, engineering, life sciences, physics and even nuclear science (the image in this post is a nuclear simulation). The writers examine the attitudes of academics, students and professionals to the use of computer simulations in their fields – back in the 1980s (hence CAD) and again in the mid 2000’s. It was intriguing to see how much things have changed – and even just since 2005 – but at the same time how much things stay the same. The argument between hand drawing and Revit models continues in many offices to this day. Personally I think it will keep on going for some time, because now even our clients have started contributing to it! One design gets up because of a sexy fly though and renderings, another client is only convinced of the quality of the design when they see some pretty hand drawn perspectives (which had in actual fact been traced over a Revit model!).

Do we think only by drawing as is so commonly stated by architects and designers? I still keep a roll of trace at my desk and use it at some point in every project, I do think while I draw. But I think while I model too. Often the model makes me think harder. Things cannot be faked and fudged in the model as easily – to do so the person modelling almost always has to make a conscious decision to fudge it, to take a shortcut. At least anyone who actually understands the building does. There are certainly those who have been taught to fudge it, make today’s drawing or image pay off, get it out the door. There are certainly times when you need to. But that’s not BIM and it’s not thinking either. To me it’s the same by hand – you can draw or trace without thinking about how something really works, if it works in 3d or from the back, how it’s built, if it complies with code. You can do the same with a model. But if you model properly, with the intent of creating something that can be built then you have to think at the same time.

Interestingly one of the biggest concerns of the “discontents of simulation” was the same for all the disciplines discussed. It was a concern that practitioners became disconnected from the reality and the physicality of their discipline – unable to judge what is possible in the real world as opposed to a simulation. In architecture there is no doubt that this problem occurs, with the number of technical detailers and specification writers (often of the grey haired variety) dropping in many offices and there not being a younger generation to replace them.

Now in the architecture profession, we could blame BIM and computer software for this problem – but is it? Does anyone really think so? We can blame a lot of things on BIM, but is it BIM or is it something else? When I read articles blaming poor design on BIM, it often seems to me it’s a different problem. The problem is about many things – most of which are outside of BIM. First and foremost it’s a lack of a transfer of knowledge. Whether that is the immediate transfer of knowledge between designer and modeller, or the lack of BIM knowledge of the designer or the lack of technical knowledge by the detailer. Why isn’t this knowledge being passed down? Is it a lack of interest in either teaching or learning – I don’t think so. I think it’s a lack of time. A lack of time (and fees) for graduates to go out on site and learn about construction. A lack of time for more senior staff to learn about BIM. A lack of time because there are so many different things we expect an architect or interior designer or engineer to do and know. Not just one BIM software but many packages for modelling, presenting and maybe even project managing and scheduling too. Its not just the amount of knowledge required either. Its the pace – every year projects seem to be delivered faster and faster – it’s not even about fees anymore – sometimes there really just isn’t any time for someone to explain what or why something is done that way – it just has to go out to the builder now.

Is this affecting the quality and cost of design? Of course it does. It’s not just the time for teaching, it’s also the time for thinking. It has been proven that as architectural fees go down, construction fees go up. While BIM can help rescue RFIs and variations – it still remains true garbage in, garbage out. This is the biggest concern of the discontents of simulation – sometimes at the end of the day the simulation is so beautiful, we could be blind to the garbage that went into creating it.

Are you an architect? Do you draw? In the sense I’m referring to that question today, it is usually meant to include modelling as well, and usually means more than just mark up or do a quick napkin sketch. Are you still an architect if your day job doesn’t involve drawing? What does an architect actually do day to day if they don’t draw? Today, the tasks that an architect do can be so broad, that many architects don’t even seem to understand what other architects they work with actually do. If we don’t understand what our colleagues are actually doing, then is it any surprise that many of our clients don’t really understand (or value) all the tasks that go into creating a building project.

I’ll start by saying, technically, I’m not an architect (although I do still draw depending on workload and projects). The reason I’m not an architect is very much a technicality, and whilst its not about drawing, I think it is relevant to the way in which the profession seems confused about itself and what architects actually do. I studied architecture for 6 years, have worked in the industry for 15 and I have even sat for and passed the Board of Architecture exams. However, I don’t pay the annual registration fee to the board, so that means I’m not an architect. (That’s my choice though, as I work as an interior designer – the relationship between designers and architects being a story for perhaps another post sometime). In Australia, anyone who not passed the exam and registered is not supposed to call themselves an architect, but a graduate of architecture, even if they have been practicing for 30 years. It’s not this kind of semantics or industry protection that I’m really wanting to talk about today (though personally I don’t think architects really benefit from the protection if the term), it’s the tasks we actually do to deliver our projects. And can often apply just as much to other building design disciplines such as interior design and engineering too.

For any architect (or graduate of architecture) or interior designer that works in an office of more than a few people, you won’t do everything yourself. Some people will undertake business development and bring in the work, some will have face to face client roles, some will draw, some will use BIM, some will know all the graphic software, some will write specifications, some will be good at the overarching idea, some will be focussing on construction and technical detailing, and someone needs to ensure that the subconsultants are briefed, the team is delivering on time and the team size and mix is the right one. Most of us do a mix of these things, very few of us are good at all of them. The whole point of working in a team (to me anyway) is to benefit from these different mixes of skills.

Given that delivering a building project is therefore very much a team sport of many different positions, it therefore surprises me then when I hear comments like “as architects is job is mostly drawing” or “what are you actually doing on the project – you are not drawing or writing the spec?” That fact that the later was made by an architect who was managing more than 20 architects (and happened to be involved with the board or architects), is to me, quite disturbing. Do architects really not understand and value what their team mates are up to on the job, thinking that only certain parts of the project are actually important to the architecture?

I guess that partially it is related to the increasing complexity of large construction projects. When I first graduated a bit over 10 years ago, we didn’t have sustainability consultants, access consultants or BIM managers – every project our consultant teams seem to grow ever larger. (Recently I saw a consultant team list which included a wind consultant – a new one to me). Managing all of these people, briefing them and coordinating their work is a big job on its own. You can then add the work often involved in meeting client stakeholder management and reporting processes, quality assurance processes and code compliance checking (which whilst we have consultants is still so much the responsibility of the designer be they architect, interior designer or engineer). Between all these tasks n a larger project you easily have a full time role, commonly referred to as design manager.

It is really important that this is understood as a different role to the project manager – whilst one person may do both, just because there is a project manager doesn’t mean you don’t need someone undertaking the tasks of design manger. In fact, sometimes it can become even more critical to ensure that these tasks are actually undertaken and don’t fall through the cracks when the independent project manager consultant is the lead consultant. They won’t generally do your co-ordination checks for you. Whilst a project manager ifs often at arms length from the actual design and documentation, and may have very different qualifications and skills to the architect – to me, the true design manager needs to understand what is being designed – they need to be an architect (or a designer or engineer depending on the project/design team being managed). However, there seem to be a lot of architects and designers who don’t understand that this role is very much a valuable and necessary one (whatever it is called), and, if the project team is structured well, not just another layer of management.

If I told an architect who sat at the computer all day writing specifications that they weren’t an architect because they couldn’t manage a 20 person team to deliver a multi million dollar project they would scoff at me. Same thing if I told the autoCAD technical detailer she wasn’t an architect because she didn’t use BIM (and had no interest in learning or even understanding why you would use it). But many these kinds of team members seem to think its ok to put down the work of those managing the projects (or even those brining in the work) as not being real architects because they don’t draw.

One of the funny things to me in all of this, is that in Australia, the registration exams actually focus on these management and practice management tasks – not on design, drawing, technical detailing or specifications. This knowledge is taken as assumed (through your studies and your log book of experience) – neither the written exam or the interview deal with these topics. So maybe it’s the opposite – real architects don’t draw? (But of course in my world they are all expected to use BIM!)
